But I’m curious whether it be now or during a vacancy if there’s an effective way to help soundproof a little better aside from the obvious open up all the drywall and insulate? 

I would advise speaking with an attorney that can help draft up the documents and understands the business you are in and the potential pitfalls so everyone is covered.

I'm really interested in creating equity in multifamily via improvements on 4 units and up.

STRs, LTRs, flips, etc Hello River, it's great to meet you.My current strategy focuses on utilizing small multifamily long-term rental properties by implementing the BRRRR method.

UPS Worldport in Louisville is the largest automated package handling facility in the world, acting as a global logistics hub and supporting thousands of jobs.

We do not represent them.And I can tell you, in almost every case we have an unrepresented buyer on my listing....I make more, the seller makes more....and the buyer is probably paying more than they would need to, and waiving things, or agreeing to contract terms that they have zero idea what they mean or is customary.As an example, almost every unrepresented buyer on my listings ends up paying 100% of the transfer and recordation taxes, when customarily those are split 50%/50% between buyer and seller.

On the 19th now the credit bureaus didn't all show up and we were forced to push it back another day because the scores didn't show until after my original  closing time.

We offered asking price + a seller credit for our closing costs and won out over a cash buyer who wasn't willing to come up to the seller's asking price (luck - we got lucky).

Cost is $150 and up for each report. 

It feels as if the shift to more of an apartment home is what helps with tenant retention.Having amenities on property, such as dog parks and fitness centers, help with retention, and being close to amenities also helps.I think the same can be said for most smaller multifamily, with having washer dryer hook ups, 2 to 3 beds, at east 1 1/2 baths, if you have some privacy for a yard would be a huge bonus.I really would stay away from pools for small multi families.
